Marked price of an article is Rs. X. A person purchased it for Rs. Y after a discount of 30 percent on marked price. He then sold it for Rs. Z. If Z is 25 percent more than X, then Z is how much percent more/less than Y?
Show answer & explanation
Correct answer: B
Explanation
Let the marked price = X
Discount = 30%
Cost price (Y) = 70% of X
Y = 70/100 × X
Y = 0.7X
Z = 125% of X
Z = 125/100 × X
Z = 1.25X
Z is greater than Y by -
= (Z - Y)/Y × 100
= (1.25X - 0.7X)/0.7X × 100
= 0.55X/0.7X × 100
= 55/70 × 100
= 78.57%
